Right, have you guys looked at something like a Clip+ or MacBook Pro? These devices are thin, and the Clip+ is pretty small too.

Could someone please check out this post, I'm literally stumped as to how charging a DAP from a different battery would affect SQ, even if you ran it down all the way!

The post contains a lot of opinion, but no real testing or proof.  

 

One theory might be that a good external power source of any kind with a low source impedance might possibly improve sound quality if the DAP is driving low impedance headphones with a complex impedance.  That's a lot of "mights" "possiblies" and "mays" though, and without some real testing, it's just biased opinion.

Do you have FCC or equivalent in UK? If so put in an inquiry to it, it might be able to help. I remembered reading some FCC publication on radio interference and solution to solve them. This mostly involves grounding. There might also be a possibility that your amp is defective because of cold solder joint (IMO, a very likely scenario..

Any way, in severve case (many people complain), FCC will send people out to do a survey and shut down the offending equipment (terminology is radiator), This is why we have FCC part A &B as well as CSPR standard to prevent excessive transmission radiation. Most goverment are very serious about it and have enforcement unit.

Sorry...why are we talking about RFI, FCC, etc?

Earlier on in the thread I was troubleshooting the RFI with my Magni which they were trying to help with
